Abstract

The invention relates to a built-in antenna of a mobile terminal, in particular to a low-profile mobile terminal antenna. The low-profile mobile terminal antenna comprises a PCB (printed circuit board) and an antenna body arranged above the PCB, wherein the antenna body comprises a first antenna body and a second antenna body, the first antenna body comprises a feed branch, a first long branch, a second short branch, a third long branch and a first ground branch, the feed branch and the first ground branch are respectively connected with the PCB, the second antenna body comprises a second ground branch and a fourth branch, and the second ground branch is connected with the fourth branch and the PCB. Compared with the prior art, the low-profile mobile terminal antenna is wide in resonance bandwidth, in particular high-frequency bandwidth, and is obvious high in radiant efficiency.

Description

technical field [0001] The invention relates to a built-in antenna of a mobile terminal, in particular to a low profile mobile terminal antenna. Background technique [0002] An antenna is a device that uses frequency characteristics to receive and transmit signals. In recent years, the design and performance of mobile terminal antennas for wireless communication have more and more influence on the development direction of mobile communication. The main indicators of antenna design include: suitable multi-frequency resonance; the antenna realizes signal propagation and energy radiation based on resonance of a certain frequency. If an antenna can resonate at multiple frequencies, then the antenna will work at multiple frequencies. On the other hand, the design of mobile terminals is becoming more and more highly integrated, resulting in smaller and smaller space occupied by the antenna. For the antenna, an important dimension is the height of the antenna, because mobile te...
